With logs up to ~25 000 entries, eagerly painting every grid cell
caused multi-second freezes on page load. Add content-visibility:
auto to the line-number and content cells so the browser defers
their layout / paint until they scroll into view.
The rule lives on the cells (not on .entry itself) because .entry
uses display: contents and produces no box of its own.
contain-intrinsic-size: auto 1.5em lets the browser remember
measured heights after first paint and uses ~one line tall as the
initial placeholder for never-seen cells.
